The men and women of the U.S. armed forces carry heavy burdens in their important service to the United States. But with the stated goal of providing a measure of in-the-field stress management assistance, the U.S. Department of Defense has released a smartphone mobile application to help service members “use the therapeutic benefits of biofeedback.”

The announcement from the DoD references BioZen as the mobile app in question.

Produced from the Defense Department’s National Center for Telehealth and Technology, the app uses wireless sensors to show users their physical level of relaxation.

The Department says this is “the first portable, low-cost method for clinicians and patients to use biofeedback in and out of the clinic.”

BioZen shows real-time data from multiple body sensors including electroencephalogram, electromyography, galvanic skin response, electrocardiogram, respiratory rate, and skin temperature. Each sensor sends a separate signal to the phone so users can see how their body is responding to their behavior.

“Mastering biofeedback successfully is difficult and frustrating for many people,” says Dr. David Cooper, a psychologist. “This app takes many of the large medical sensors found in a clinic and puts them in the hands of anyone with a smart phone. BioZen makes it easier for anyone to get started with biofeedback.”
